High tensile Socket Cap bolt allen bolt black surface treatment

Short Description:

Socket Head Cap Screws, or Socket Cap Screws, are threaded fasteners with a cylindrical head and a recessed hexagon drive. Socket screws are turned by using a hexagon shaped key and can be tightened to much higher torque specifications than a crossed recessed or slotted drive fastener. Socket cap screws are often used in applications like machine parts, die fixturing and clamping where there is not sufficient space for wrenches or sockets.

Product description

Heat treatment lines are introduced as we completely understand the importance of heat treatment as an integral supplement to decent quality forging. High tensile socket cap screws are made of medium steel or alloy steel. These screws need to be heat treated, then the grade of tensile strength would be no less than 8.8. We have full experience in heat treatment and will conduct a series of complete testing and inspections, such as chemical tests, mechanical tests, hardness tests and salt spray tests for each batch of order. All socket cap screws must be in conformity with the related international or domestic standards before shipment.
We will pack the screws as per your requirements or the standard export packaging to avoid any possible damages to the screws in transport process. Usually, our fasteners are packed in gunny bags or cartons, 25 kilograms or 50 kilograms per gunny bags, 25 kilograms per carton. Then bags or cartons are placed onto the pallets. In addition, the pallets would be wrapped up by polyethylene film to keep moisture from penetrating during ocean shipping.
